Stay naturally cool with the TOP-EX ChillFlex Runner Cap—no water needed. It delivers a cool-to-touch sensation the moment it meets your skin. Unlike typical wet-to-activate hats, our cooling effect is instant, dry, and woven into the fabric. TOP-EX cooling mesh adapts as you do: enjoy dry contact cooling for daily workouts, a deeper chill after soaking for extreme heat, and airflow-boosted refreshment when you're in motion. Our advanced fabric technology offers three levels of cooling—experience it during your toughest summer runs, hikes, or golf rounds. Stay protected with UPF 50+ double-layer mesh shielding you from UV rays without sacrificing breathability. The flexible visor bends any way you need and recovers effortlessly, while the lightweight, foldable design fits easily into travel bags or gym lockers. With stretch-fit sizing, sweat-wicking performance, true oversized fit options, and reflective accents for visibility, ChillFlex is ready for wherever the heat takes you—running, golfing, hiking, working out, or just living your outdoor life. Available in M/L (7 1/8 – 7 3/8 US / 22.4" – 23.2"), L/XL (7 1/2 – 7 5/8 US / 23.6" – 24.4"), and XXL/3XL (7 3/4 – 8 US / 24.8" – 25.6").
